Letters Patent No. 114,330, dated May 2, 1871.

IMPROVEMENT lN co FEE-RoAs ERs.

The Schedule referred to these Letters Patent and making of the same.

I, AUGUSTIN OBST, 'of "Gambridgeport, in thecounty of Middlesex and State of vh/Iassachusetts,

have invented certain Improvements in Ooifee-RoasM er, of which the following is a specification.

'Fig ure l is a sideelevation, and

Figure 2 a transverse vertical centralsection of my invention.

The object of this invention is to provide a convenient and simple device for roasting coffee, 850.; and

consists, mainly, of a frame or plate of a shape con- ,a shaft, E, which has its hearings on the upper side of frame or plateB, which latter is provided with a rectangular orifice of sufficient size to allow the cylinder A to project through the same. The plate B is provided with a flange around its edge, and is shaped to conform to the orifices in the top of a cooking-stove.

I represents the handle of a; clamp, J, which is. pivoted in one side of plate B, and by being turned, as

'shown in the drawing, secures the plate B to the stove,

said clamp bearing against the lower side of the upper plate of the same.

0 represents a semi-cylindrical lid or cover, which is hinged to the plate B, and exactly covers the rect-:-. angular orifices in the sanie, thus inclosing the cylinder A from without, and reflecting the heat from the fire below upon the cylinder A.

K'represents a latch, which holds the cover Oin placeon plate B.

Said cover maybe attached to said plate by ninges, H, as shown, or may rest thereon and be removed by the knob L.

D represents a slide in the cover 0 to ventilate the same when the'temperature inside becomes too high.

L is a slide in the cylinderA, by means of which access is bad to the interior of the same.

Motion is imparted to the cylinder Aby means 0 the crank F. g This arrangement constitutes a simple and efiicient roaster for coiiec, 8m, and iswell adapted to domestic use. 7

Having thus fully described my -invention,

\Vhat I claim as new, and desire to secure by Letters Patent, is- The combination of frame or plate B, cover 0, clamp J, and cylinder A, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing .Auens'rm OBST.
